FAQ

Product Details

Is this Spax screw suitable for countersunk applications?

Yes. This model has a countersunk head, which is designed to sit flush in countersunk or prepped materials for a neat finish.

What drive type does the screw use?

It uses a PZ drive, specifically a PZ cross slot. That means you will need a compatible Pozi screwdriver or bit for best engagement and reduced cam out.

What does the 4.5 mean on the “4.5x50mm” sizing?

4.5 refers to the thread diameter, so the screw is sized for a thread Ø of 4.5 mm. The 50 mm is the overall screw length, giving you an easy way to select the right size for your timber or board thickness.

Is the screw fully threaded or partially threaded?

It is fully threaded, which helps provide stronger pull through along the full length. This is often useful for fixing where you want consistent grip from head to tip.

Why is the screw yellow, and what does the coating help with?

The yellow finish is a chromated coating intended to provide improved corrosion resistance compared with uncoated steel. It is designed to help the screw perform reliably in typical building and furniture fixing conditions.

Does this screw have a square tip feature, and will it help with starting?

Yes. The tip is described as a square tip with a patented shaft profile, which can make it easier to start and drive the screw cleanly, especially compared with smooth or harder to start screw tips.

How many screws are included in the pack?

There are 200 screws per pack. This is a practical quantity for multi site jobs, repeated tasks, or larger projects where you want to keep to one consistent screw size and specification.
